Filling or moving holes AutoCad 2007

[Berzerker]

Hope you  all don't mind me asking different questions about different things in the same post but I don't want to just keep making threads.

How do you change the dimensions from inch to mm. I went into my settings and changed it there but it still measures in inches.

My version doesn't have DWGUNITS command. I remember something about DIMUPDATE or something like that. I have went into Dimension Style and set up style called Millimeters but still no change. I'm probably missing just one thing I forgot.

Thanks

 

Edit: I forgot to set as current......go figure

DWGUNITS is a system variable, and as far as I know, it has always been available in all versions of Autocad. Are you sure you typed it correctly? You might need to put a dash in front, like this -DWGUNITS.

 

Edit: Oops, I guess you're right. I just did a search and found that it started with version 2009.

Haven't got around to checking out fusion yet either. Yeah I looked it up too that's how I knew. Everywhere you go they think everyone has the latest and greatest  AutoCad.

I'd give anything to be able to afford it. Only now you (RENT) AutoCad not buy it. At $1700 per year, 

As far as Fusion is concerned I know there will be a learning curve and I wanted to get my project to the 3D printer.

I have moved your thread to the AutoCAD 3D Modelling & Rendering Forum.

I thought most 3D printers used supports to hold up the over hung places. After printing to just break off the support tabs and clean with a nail file.

I'm not real sure (?) The printer is not mine, I'm having a friend do it for me.

Yes, the printer will add supports for parts that overhang, but I see that your cover is somewhat enclosed which is why I mentioned it. The printer might add supports in there that could be difficult to remove, or it might not. Does your friends printer software have the ability to run a virtual simulation to see where the printer will add supports?

We had talked about it before but I'm not sure. The only way I know to check is let him try to run it on the printer.

You may need to glue 2 parts together so no internal supports that you can not get at to remove.

I sent him the .3mf file but he's a Master Sergeant in our Great National Guard and he's doing his two week thing. I won't be able to find out till he comes home and he's able to get around to it. If I have to do that it will be fine. I'll just slice off the top and make it two pieces.

Don't know how old you guys are and I can't remember if I told you but when I was young I owned a pair of speakers called "Mindblowers". I have been looking for a working pair for years.

I found an old pair in a box in one of my closets (not working). So I wanted to see if I could buy the parts to fix them (?) Long story, short....They don't make some of the parts for them anymore (it was the 70's). I taught myself enough electronics to understand how small amplifiers worked and designed an updated model. This is the cover that will cover the electronics on the bottom of the speaker.

Here is a video of how they use to look:

"Warning turn your speakers down"

Well, lets just say that I started using Autocad version 10 back in 1989, when I was in my early 20's. So I've been around for a while.

 

That's a cool project. Taking something old and making it new again. I'll be interested to see how this progresses and to see, and hear, the finished product.

[Berzerker]

I'm 59 Cad64. I had to learn PCB design, electronic component editing and basic electronics to even get started.

Here's some of my work.

The one with the components on it is a buck converter (step up) I couldn't get the watts I wanted without going to an higher voltage (16 volts).

I went with a IC (intergraded circuit) instead if a whole bunch of separate components. The old mindblower said 30 watts on the box but some people said when measuring the watts it came out at 70 watts. I know they were loud! here's also a pic of the old style.

The old style was more of a simple guitar amp.

I don't know much about electronics but this looks like it would be a pretty fun and challenging project. Hopefully your friend can get the cover printed sooner rather than later so you can continue working on it.

[BIGAL]

Post the dwg can test making the part and see how much support required, sometimes you print upside down to reduce supports. yes I have a printer. 

 

I still think two pieces glued together no support then. Bottom and right top. The top printed upside down.

It would be much appreciated BIGAL. The .stl file doesn't come out to scale right. I had to times them by 25.4 to make them correct in Cura.

I uploaded the CE4 file and the .stl. The CE4 file has the correct scale values.

The numbers should be:

X = 101.6

Y = 171.4453

Z = 73.025

 The CE4 is just how Cura saves the files after you've changed values in it. I don't know what program your using.

And again Thanks.

You can see all the infill material thats why I would suggest do in 2 halves slice top off turn upside down if support required will at least be on outside. 

 

 

Maybe even print the top flat plate seperate then hopefully only a small amount of support at base of inclines. The 3d printers have a max incline angle without support. This would significantly reduce time.

That's what I was concerned about, with that overhang and enclosed area. All that support filling.

Thanks BIGAL! what really got me was the 4 days,16 hours and 29 minutes and all the wasted wire. I know 3D printers aren't fast but geez. Is this called slicing on the program? I only went so far because I didn't have a printer. I haven't got around to really trying out the program because I didn't want to mess anything up with my drawing going to print.

I guess what I'm asking can I do this to check it out myself even if I don't have a printer attached? If it is the "slicing" part is that kinda like "print preview" on a paper printer?

What program do you use? Hope you don't mind me asking all these questions. If I had a 3D printer I'd be like a kid in a candy store, printing everything in sight like a sugar rush!

I'll cut my part into 3 parts. Seeing what I saw on your pic I think it might be easier, better and faster.

 

OH and I'm not leaving you out Cad64...Thank you guys for everything!

Your Cura software should allow you to see a preview of your part, including the supports. I don't know if you need to have a physical printer attached though? Does the software allow you to choose a virtual printer, or can you select a default printer from a list that you could use for previewing your part?

[steven-g]

I think the 4 days,16 hours and 29 minutes is giving BIGAL 4 days allowance for his new filament to arrive, and probably another half a day to put it in the printer. Cura gave just under 8hrs with 28M of filament (but this obviously depends on so many settings like actual size and infil

@Cad64 

I'll have to look and see if it will let me select a virtual printer. I'm working on two things today. I cut my cover into 3 pieces and I'm trying to setup a old computer as a printer server.

 

@steven-g

Yeah, I thought that sounded a little long but you never know.

I attached the new cover file and a pic. I put line up tabs on it. I'm checking to make sure they line up.....You all know how bad I am at 3D and solids.
